Normal human pancreatic duct epithelial cells

Culture medium	RPMI-1640 complete medium: 90% RPMI-1640 + 10% FBS
Subculture procedure	Recovery steps: ① Take out the frozen vial from liquid nitrogen or -80 ℃ and put it into PE gloves, quickly subtract into a water bath pot at 37 ℃, shake the frozen vial to accelerate dissolution, and completely dissolve within 1 minute. (2) Add the dissolved cell solution into a centrifuge tube containing 9ml of complete culture medium in an ultra-clean table, centrifuge at 1000-1200rpm for 5min, discard the supernatant, resuspend the cells with 1-2ml of complete media. ③The cell suspension was then added to the T25 flask containing 5-6mL of complete medium and placed in an incubator for culture. Cell subculturing: ① remove the medium, rinse twice with PBS, and add 1-2mL pancreatin (0.25% Trypsin + 0.02% EDTA); (2) Observe the digestion situation under the microscope. When the cell edge shrinks and the adherent is loose (a pasteur pipette can be used to suck out a little pancreatin and gently blow somewhere in the cell layer, the cell layer can be seen to detach with naked eyes, that is, digestion is completed, otherwise digestion is continued), directly suck out pancreatin add 5-6ml of complete medium, gently blow the cell layer off. ③ Dispense the cell suspension into a fresh T25 flask as the ratio of 1:2, add appropriate complete culture medium, mix the cell suspension evenly, and culture in an incubator. ④ Pay attention to the change of pH of medium and cell density, renew the medium regularly (2-3 times a week), and repeat the subculture or cryopreservation when the cell density reaches 80%-90%.
Growth conditions	Culture temperature 37 ℃; Atmosphere 5% CO2 + 95% air;
Growth characteristics	Adherent growth
Storage conditions	Liquid nitrogen
Type	Epithelial cells hTERT-immortalized cells
Safety level	2
morphology	Fibroblast-like, long spindle
Separation substrate	Pancreas; Tube
application	Exposure of hTERT-HPNE cells to sodium butyrate and 5-aza-2 '-deoxycytidine resulted in the formation of pancreatic ductal cells 7, 8, and 19 marked by p-glycoprotein (multidrug resistance (MDR-1)), carbonic anhydrase II, and cytokeratin expression. hTERT-HPNE cells were found to have the properties of intermediate cells formed during acinar-to-ductal metaplasia, including their undifferentiated phenotype, expression of nestin, and evidence of active Notch signaling Ref.

Receiving notice:

1 Upon arrival, it is suggested to sit the cells in a incubator for about 4 hours, and then renew the media for recovery or subculture according to the cell density.

2 If the adherent cells are received in the form of ( partial) suspension, please centrifuge the suspended cells in time, add 15% serum complete medium to a fresh culture dish / vial and continue to culture for 3 days; At the same time, the remaining adherent cells in the original culture flask were renewed with 15% serum complete medium and cultured for 2-3 days. If the cells do not proliferate after 3 days but continue to detach and die, please contact the technicians.

3 Slow growth of adherent cells: properly increase the serum concentration (no more than 20%) or transfer to a fresh culture flask for further culture after trypsin digestion according to the cell density.

4 Uneven growth: if adherent cells grow unevenly and is island-like, they can be digested, dispersed, and cultured with fresh medium.

Recovery and subculture procedure ( under strict aseptic conditions )

1 Remove the medium in the original culture flask, rinse twice with PBS, and add 2~3 ml of 0.25% EDTA for trypsin digestion (usually in 1~2min)

2 Observe the digestion under the microscope. When the cell edge shrinks and adherent is loose (but not floating), remove the trypsin, add 6~8ml complete medium, aspirate the cell layer off.

3 Transfer part of the cell suspension to a fresh culture vessel / flask, add appropriate complete medium, and culture it in the incubator.

4 Pay attention to the change of pH value of medium and cell density, renew the medium regularly, and repeat the subculture or cryopreservation when the cell density reaches 70%-80%.

Special attention: (if handle in public laboratory or first time to culture the cells, it is recommended to add penicillin streptomycin into the media)

1 Upon the receipt of the cells, renew the solution with fresh 10% FBS medium as soon as possible. It is not recommended to use the medium used for transportation in the original bottle.

2 Please take photos and contact the technicians in time if the culture flask leaks upon the receipt of cells.

3 Any compliant on the cells, please take photos and contctat our technicians.
